TPO membranes are composed of a blend of thermoplastic polyolefins, typically ethylene propylene rubber (EPR) and polypropylene (PP). This combination provides the membrane with desirable properties such as flexibility, durability, and resistance to weathering.
TPO pre-paved membranes are specifically designed to provide a reliable waterproofing barrier. They effectively prevent the penetration of water and moisture, protecting the underlying structures from water damage.
TPO Waterproof Membrane specification:
Item | Product specification |
Coil length | 20m or as agreed by both parties |
Coil width | 1m,2m |
Coil thickness | 1.5mm,1.8mm,2.0mm |
or as agreed by both parties |
Weldability: TPO membranes can be easily heat-welded together during installation, creating strong and seamless seams. This thermoplastic characteristic allows for efficient and secure connections between membrane sections, ensuring water-tight integrity.
Chemical Resistance: TPO membranes display good resistance to chemicals commonly found in construction environments, including acids, alkalis, and solvents. This resistance helps maintain their performance and integrity when exposed to potentially damaging substances.
Applicable to underground construction (base plate, external defense inside paste side wall), tunnels, pipe corridors, culverts and other waterproofing projects.
